“…Although not always reconstructed in paleo-tectonic reconstructions, in the early Neoproterozoic, the position of Svalbard was probably close to the Timanian margin of northern Baltica prior to the opening of the Asgard Sea and Iapetus Ocean/AEgir Sea (Torsvik et al, 1996;Cawood et al, 2001Cawood et al, , 2010Cawood and Pisarevsky, 2017) and prior to the Timanian Orogeny in the late Neoproterozoic (Roberts and Siedlecka, 2002;Roberts and Olovyanishnikov, 2004). In northern Baltica, similar, steep, abundant, WNW-ESE-striking, margin-oblique (i.e., oblique to the Atlantic margin) brittle faults were mapped on the Varanger Peninsula (Siedlecka and Siedlecki, 1967;Siedlecka, 1975;Siedlecka, 1980) and Magerøya (Koehl, 2018;Koehl et al, 2018c) in northern Norway, and these represent fault segments of a major, inherited, Neoproterozoic subvertical fault, the Trollfjorden-Komagelva Fault Zone, which formed during the Timanian Orogeny and is thought to have accommodated hundreds of kilometers of lateral displacement (Rice, 2013). This fault experienced multiple episodes of reactivation and was last reactivated under transtension; shortly before it was intruded by Mississippian (Visean; Lippard and Prestvik, 1997) dolerite dykes that seal the fault (Roberts et al, 1991;Nasuti et al, 2015).…”
